The paper presents an analysis of basic problems of signal formation by a moving object as problems of wave radiation and reflection with allowance for moving boundaries. The inverse problem is considered: reconstruction of the law of displacement of an object based on the known shape of the probing and reflected waveforms. The spectrum of the harmonics generated by reflection from an incrementally moving and oscillating obstacle is found. The correlation function of the noise emitted by a moving object is calculated. General considerations about the transient radiation of a flying body in restrained urban conditions are presented.

运动物体：无源，有源位置和瞬态辐射的信号频谱

本文对运动物体形成信号的基本问题进行了分析，如允许移动边界的波辐射和反射问题。考虑了反问题：基于探测波形和反射波形的已知形状来重建对象的位移定律。找到了由不断移动和振荡的障碍物反射产生的谐波频谱。计算运动物体发出的噪声的相关函数。提出了关于在受限的城市条件下飞行物体的瞬态辐射的一般考虑。
